Product Description

Application in synthetic fibers

DMSO was used in acrylic spinning. The first patent application by Toyo Rayon Co., Ltd. was to polymerize acrylonitrile in DMSO without separation, and spin it directly in a water bath to obtain bulky, soft, and easily dyeable artificial wool. Its advantages are simplified process, high solubility, high solvent boiling point, non-toxic, easy recovery, good product performance and low cost. Some acrylic fiber factories in Yuci, Dalian, and Beijing in Shanxi, China use this process. Recently, it is also used in the production of carbon fiber with polypropionitrile. It is used for the refining of terephthalate in the production of polyester resin abroad. In addition, DMSO spinning and acrylonitrile copolymerization are used in the production of chlorinated fiber.


Application in pharmaceutical production

DMSO is used as a reaction solvent in the synthesis of pharmaceutical intermediates. For example, fluorochloroaniline is prepared by the reaction of potassium fluoride and 3,4-dichloronitrobenzene in DMSO, which is widely used in the production of norfloxacin and fluorine-containing drugs such as trifluoronitrotoluene and ofloxacin. India is one of the main countries producing fluorine-containing drugs, so the annual import volume of DMSO is about 4500t. DMSO has been used in the production of berberine, inositol nicotinate, sucrose fatty acid polyester and extraction of traditional Chinese medicine.
